It does not transfer matter during the energy transfer. Electromagnetic wave Electromagnetic waves are created by accelerating charges.EM waves are composed of oscillating magnetic and electric fields. Electromagnetic waves are formed when an electric field couples with  magnetic field. Both fields…
